CU-AL Technology
Disassembly of CU-AL Transfer Products
With the growth of global photovoltaic installed capacity, power station construction has shifted from "extensive expansion" to "fine cost reduction", while expanding the area of photovoltaic projects, people began to pursue a balance between cost and quality. The electrode potential difference between copper and aluminum will form a galvanic effect, accelerate the oxidation of aluminum in a humid environment, increase contact resistance, and cause local heating. SUNKEAN copper-aluminum transfer wiring harness products handle complex pre-connection issues for customers before leaving the factory.

Advantages
Why Choose SUNKEAN CU-AL Solutions?
Although traditional copper core cables have excellent conductivity, the high cost of raw materials and weight disadvantages seriously restrict the cable deployment efficiency of large ground power stations and the return on investment of distributed projects. In this context, aluminum conductor solar cables have become the key solution to solve the contradiction between cost and performance with material innovation and process upgrades.
Eliminating Brittle Fracture Risks
The innovative welding process completely avoids the brittle fracture risks associated with traditional fusion welding, while achieving near-zero thermal damage to conductivity, ensuring stable power transmission for over 25 years.
Economical and Efficient
Compared with copper, aluminum has 58% lower cost, abundant resource reserves, and is lighter in weight than the all-copper solution, which can reduce transportation costs.
Superconducting Performance
With TÜV Rheinland and TUV SÜD IEC 62852 dual certification,the specially designed crown spring structure significantly reduces contact resistance and increases current carrying capacity. The annual loss of 1500V system is reduced by 1.2 MWh/MW.
Durable and Corrosion-Resistant
Utilizing a nano-level, four-dimensional gradient coating technology, from inhibiting ion migration at the base layer to resisting extreme environmental corrosion at the surface, ensuring the connector maintains excellent corrosion protection in various harsh conditions and providing 10-year warranty service.
Intelligent Assembly
The quick-plug design reduces installation time to less than 1 minute, and the self-locking mechanism ensures a safe and reliable connection. It has strong compatibility and is compatible with various mainstream connectors like MC4.
Green and Environmentally Friendly
Using a green production process with low energy consumption and zero emissions, 95% of aluminum cable materials can be recycled, reducing carbon emissions over the entire life cycle by 60%-95%.

Aluminum Alloy Photovoltaic
Choosing aluminum alloy photovoltaic cables makes solar power station construction more economical and efficient.
In the current scenario of continuous escalation in copper prices, the cable industry frequently faces incidents of copper wire theft. This not only brings significant economic losses to enterprises but also poses serious safety hazards. Many manufacturers have begun to adopt and promote aluminum conductor connection solutions.To address this challenge, we have developed the Aluminum Alloy Photovoltaic Solution, which replaces traditional copper materials with innovative aluminum alloys. This substitution effectively reduces the risk of theft and enhances the safety and stability of systems.
Rooftop Solar Power Stations
In industrial and commercial building rooftops, as well as residential rooftop solar systems, using aluminum alloy photovoltaic (PV) cables can reduce the load on the roof, thus lowering the structural stress on the building. Additionally, the lightweight and flexible nature of aluminum alloy cables makes the installation process easier and quicker, saving time and labor costs.
Rural Solar Power Stations
Building aluminum alloy solar power stations in rural areas provides clean energy to these regions while also reducing the risk of cable theft, thereby enhancing the stability of the power system.
Large-Scale Solar Power Stations
In large-scale ground-mounted solar power stations, using aluminum alloy PV cables can significantly reduce the overall wiring cost. Aluminum alloy cables are more cost-effective than copper cables and lighter in weight, which can reduce the cost of supports and installation structures, and also facilitate large-scale deployment and maintenance.
